篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了怎样在网页中做出瀑布流效果?相关的知识,希望对你有一定的参考价值。

  在网页中实现瀑布流效果方法:

  1.传统多列浮动

  各列固定宽度,并且左浮动;

  一列中的数据块为一组,列中的每个数据块依次排列即可;

  更多数据加载时,需要分别插入到不同的列上。


  2. CSS3 定义

  由 chrome/ff 浏览器直接渲染出来,可以指定容器的列个数,列间距,列中间边框,列宽度来实现;

  #container

  -webkit-column-count: 5;

  /*-webkit-column-gap: 10px;

  -webkit-column-rule: 5px solid #333;

  -webkit-column-width: 210px;*/


  -moz-column-count: 5;

  /*-moz-column-gap: 20px;

  -moz-column-rule: 5px solid #333;

  -moz-column-width: 210px;*/


  column-count: 5;

  /*column-gap: 10px;

  column-rule: 5px solid #333;

  column-width: 210px;*/

  

  column-count 为列数; column-gap 为每列间隔距离; column-rule 为间隔边线大小; column-width 为每列宽度; 当只设置 column-width 时,浏览器窗口小于一列宽度时,列中内容自动隐藏; 当只设置 column-count 时,平均计算每列宽度,列内内容超出则隐藏; 都设了 column-count 和column-width,浏览器会根据 count 计算宽度和 width 比较,取大的那个值作为每列宽度,然后当窗口缩小时,width 的值为每列最小宽度。


  3.绝对定位

  可谓是最优的一种方案,方便添加数据内容,窗口变化,列数/数据块都会自动调整。

在原有基础上,远程添加图片

<div id='controls-bottom'> 
    <input class='control-input one' placeholder='添加一张图片的URL看看效果!' type='url'> 
    <div class='control-button bottom-one'>Append</div> 
</div>

js实现无限瀑布流

瀑布流

是一种常见的网页布局方式,在许多网站中我们都能看到“瀑布流”的效果,其特征是有网页视窗有多个高度不同宽度相同的“块”组成。因其样式酷似飞流直下的瀑布,

故将这种布局方式称为瀑布流。

生活中瀑布流实例:

花瓣网

技术图片

 

在css中我们学习过使用Multi-columns来实现瀑布流的效果

通过 Multi-columns 相关的属性 column-countcolumn-gap 配合 break-inside 来实现瀑布流布局。

现在,我来介绍一下如何通过js方式来实现瀑布流
